What is the primary use of the well counter in nuclear medicine?

• A. Detect alpha emissions
• B. Measure radioactivity in liquid samples
• C. Assess patient uptake in tissue
• D. Monitor environmental contamination

Answer: (B)

The primary use of the well counter in nuclear medicine is to measure radioactivity in liquid samples. This device is designed to quantify the radioactivity of liquid samples, such as those from blood or urine, which are common measurements in nuclear medicine practice. The well counter features a detection well that can accommodate vials or tubes, allowing for efficient counting of emitted radiation from the radioactive isotopes present in the sample. This capability is crucial for various applications, including quantitative analysis for diagnostic purposes and therapeutic monitoring. The well counter helps healthcare professionals assess the level of radioactivity accurately, which is essential for safe and effective patient care. In comparison, the other options do not align with the primary function of the well counter. For instance, detecting alpha emissions typically requires specialized detection systems like alpha detectors, while assessing patient uptake in tissue involves imaging modalities like SPECT or PET scans rather than measuring liquid samples. Monitoring environmental contamination often utilizes survey meters or different types of gamma radiation detection instruments tailored for ambient radiation surveys.
